We spend most of time at indoor homes, workplace, offices, schools, hospitals, factories or even at the shopping malls e.t.c. The buildings may have good or bad indoor air quality (IAQ). Bad indoor air quality leads adverse impacts. If the Indoor air quality is not so good and tends to get poor then it affects the health, and the apparent effects get severe ultimately causing death. This study focuses on the assessment indoor air CO2 in classrooms of the educational institutes. To conduct the research work, many important studies from literature are surveyed and the standard followed internationally for the normal and abnormal levels of indoor air CO2 are kept as reference to rate the measured values. For the purpose of analysis, one government school, two private schools and two private centers are selected. During various visits to the institutions the required physical data regarding dimensions and conditions of classrooms are collected, which consists of number of doors, windows with dimensions and location, ventilation mode and number of fans etc. For noting these results, a data sheet is used. A questionnaire is also used to know the perceptions of teachers of these institutes about the impact of IAQ on the performance of students, teachers and several factors are analyzed in SPSS software. The indoor air CO2 is found to be in fair, good and excellent ranges in most of the institutes. However, in some classrooms, the CO2 concentrations is in higher ranges indicating the possibility of contaminated air, and this demanding more ways of ventilation.","PeriodicalId":294515,"journal":{"name":"5TH INTERNATIONAL CONFERENCE ON ENERGY, ENVIRONMENT AND SUSTAINABLE DEVELOPMENT (EESD-2018)","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116075707","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The removal of wastewater from processing industries using chromium has been an emerging and challenging research field these days as it causes several health problems. In this study, hydrochars were generated from eucalyptus sawdust (ESD), corn straw (CS) and corncob (CB) via microwave- assisted hydrothermal carbonization (HTC) of waste biomass. The carbonized material was further treated by different alkali modifications (KOH N 0.01, KOH N 0.05 and KOH N 0.1), targeting the efficient removal of Cr (VI) from aqueous solution. Microwave-assisted hydrothermal carbonization (HTC) temperature was kept at 220 °C. Adsorption parameters such as pH, temperature, hydrochar quantity and reaction time were optimized. Adsorption experiments were carried out for Cr(VI) removal where: pH 2, 25 °C, and 2.5 g/L hydrochar quantity were found as optimum conditions. Adsorption capacity (mg/g) at equilibrium conditions was found as 34.07mg/g, 30.15 mg/g, 29.46 mg/g for ESD, CS and CC, respectively, which were compared with commercial activated carbon as a control. SEM, BET and FTIR analysis were carried out to determine the surface morphology, surface BET area and functional groups of the hydrochars. These results indicated that hydrochars (from waste biomass) modified by KOH treatment have the efficiency to remove Cr(VI). The findings of this study suggested that the hydrochars from waste biomass could be considered as the low cost adsorbents for Cr(VI) removal and this would help in environmental applications for heavy metals removal.Chromium is widely present on earth’s crust.
